High-resolution modelling of meteoroid ablation
Popis výsledku v původním jazyce
The structure and composition of meteoroids is of great interest because of the insight it provides into their parent asteroids and comets. Recently acquired, high-resolution video measurements of meteors will be used to evaluate two models of meteoroidablation. en meteors were observed with the Canadian Automated Meteor Observatory (CAMO), which uses pairs of mirrors to track meteors telescopically in the sky with a resolution of up to 3 meters per pixel. Two meteoroid ablation models were used to fitthe wide-field light curves and deceleration measurements of the meteors, and the wakes predicted by each model were compared to the wakes measured in the telescopic system. Both models produced satisfactory fits to the wide field measurements, but bothwere very poor at predicting the narrow field brightness profiles of the meteors. Models of meteoroid fragmentation in the atmosphere need significant improvement to match observations. Data from the CAMO observatory mirror systems provi
